how to change user agent in chromium embedded framework in c#?

Question

Please help me changing user agent of chromium embedded framework in visual c#. It uses default chromium agent but i want to change it to use my browser name instead.

Just for information, I found the current default to be "User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36" for CefSharp 51.0.0 — CRice, Sep 07 '16 at 06:46

Use CefSettings.UserAgent. Also it can be configured via "user-agent" command-line switch.

CefSettings is class what instance passed at initialization step. Look into samples. You can't initialize CEF without it, so, i'm did not see what should be explained step-by-step. Read samples. Both, C++ and C#. There is easy, and almost same. – Dmitry Azaraev Mar 26 '14 at 23:22
i mean what tag, namespace, etc should i use in my project? – user3463182 Mar 27 '14 at 04:05
I'm did not understand what additional details you want. If you are CEF user, you should know about CefSettings class. – Dmitry Azaraev Mar 27 '14 at 18:30
I have done the following changes....... in cef web browser [DefaultValue("Mozilla/5.0 (Windows NT 6.2; rv:13.0) Gecko/20100101 Fire/1.0")] public string UserAgent { get; set; }----------------------------- and my form---------------- browser.UserAgent = "Mozilla/5.0 (Windows NT 6.2; rv:13.0) Gecko/20100101 Fire/1.0"; yet it does not work – user3463182 Mar 28 '14 at 03:13
Did you found CefSettings class? It has UserAgent property. It should pass into CefRuntime.Initalize method. – Dmitry Azaraev Mar 28 '14 at 17:34
This dialog is non-constructive. User agent can be changed, as i'm say in my answer. – Dmitry Azaraev Apr 02 '14 at 21:55
"In detail, step by step" instructions are dependent on your local environment and skillset and are therefore chargeable service you have to seek privately. Good luck. – Piotr Farbiszewski Aug 09 '22 at 11:03

Step by step:

Download XIlium cefglue and update the dlls. If you need any help in that use http://umaranis.com/2013/10/16/how-to-embed-chrome-browser-in-net-application/
Open your xilium cefglue application.
In solution explorer open CefRuntime.cs
There will be a public static void Initialize(CefMainArgs args, CefSettings settings, CefApp application, IntPtr windowsSandboxInfo) method, inside that method write settings.UserAgent = "Sonal";
Rebuild and run the application.
In the browser give the the following url: http://whatsmyuseragent.com/
You can find the Useragent as Sonal

Hope this helps
